All the links are in the email and on the X3DSAIL page. Here are a few
repeats.
For X3D Example Archives, the .x3d models are checked into SourceForge
version control as master versions. The conversions (for instance to .py)
are on the web page for each model. See the Hello World example in the
email.
The unit test examples are all easily inspected and tested. See
- Python X3D Package x3d.py - Examples
- https://www.web3d.org/x3d/stylesheets/python/python.html#Examples
There are still some conversions that need work to handle the Comment class
feature you requested. It is a good translation feature, but has required
multiple days of debugging. Nevertheless over 90% of the translations are
correct, and I will keep working on adjusting the others. If you want to
check on correct syntax, status log is found as follows... search for
"SyntaxError:" to see failures.

While some .x3d to .py conversions are still misplacing a round parenthesis
or square bracket, python detects that instantly and (as usual) they will
eventually get fixed. Fiddling around with the Python-provided IDLE editor
(for example) can quickly fix such errata. Meanwhile there are no known
errors in the x3d.py module, so the release is solid.
Thanks for further testing and use of the library. Have fun with X3D
Python!
all the best, Don
